SELF-HEATING SAD-IRON.

Specification of Letters Patent.

Patented Aug. 20, 1912.

Application filed December 9, 1911. Serial No. 664,835.

To all whom it may concern. 1

Be it known that I, JOHN THOMAS HAR- IusoN, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have in vented certain new and usefulImprovements in Self-Heating Sad-Irons, of which the following is aspecification;

My invention relates to self-heating sad 'irons.

The object is to simplify the construction of such irons and make themof few parts and avoid intricacies in the making and the handling,combined with increased efficiency, thereby extending their durability,scope and usefulness.

In the drawing, Figure 1 illustrates a full side view of my invention.Fig. 2 is ,a full rear end view of Fig. 1. Fig. 3 is a plan view of Fig.1 with the cover removed. Fig. 4 is a full transverse section taken ata, a, of Fig. 5. Fig. 5 is a longitudinal:sectional elevation at thecenter of the sad iron.

Similar figures refer to similar parts in the different views. 7

In the drawing, 1 is the handle secured to handle carrier 2. The handlecarrier has lugs 3 to fit in recesses on top of cover 4, 5 is adeflector which has lugs 6 to fit under the cover 4. A bolt 8 serves tofasten together the handle carrier 2, and the cover 4 and the deflector5.

The cover 4 is secured to the body 9 of the sad iron by means of a lug10 on the cover which enters the recess in the forward part 11 in thebody 9. The body 9 has a tapped hole 12in which a headless screw 13 isinserted and screwed down to hold in place the burner '14, which has itsfree end resting in the hole 15 in body 9. A thumb screw 16 screwed intotapped hole 12 serves to secure therear end of the cover to the body 9.By means of thumb screw 16 and lug 10 the cover 4 is firmly secured tothe body 9; which is the general condition for use in ironing. When itis desired to use the body 9 as a cooker, or for heating, the cover 4 isreadily removed by unscrewing the thumb screw 16 and lifting the coveroff.

The body 9 is cast so as to leave openings 17. 17. between it and thecover 4 on the sides and openings l8. 18. at the rear end which allowair to circulate over the deflector 5 and thus keep the handle bar cooland also serve as escape openings for the burnt gases. The openings 17,17, of course are so arranged as to leave edges or parts 19 in the body9 of suitable extent to carry any desired cooking utensils. The bottom20 of body 9 is filled in and thick at the sides at 21, 21, so as tofacilitate the casting. This filling-in 21 terminates with heatreceiving and conducting ribs 22 from which extend, inwardly, lugs 23,which serve as arches over the air supply holes 24 drilled in the body9. The air supply holes are drilled so as to pass through the lugs andalso further so as to form grooves 30 in the bottom 20 and said grooves30 terminate close to the gas outlets in the burner.

The burner 14 is supplied with gas exit holes 25 so arranged as to be inline transversely with the air inlet holes 24. The air inlet holes aredrilled so that part of the holes or passages extend in toward theburner 14 and beyond the lugs or arches 23 so that the air and gas shallmix properly and produce a blue and intense heat flame against theinside of bottom 20, and arch 23 and ribs 22, thereby heating the bottom20 very effectively without any waste or loss of gas. The burner 14extends out and has an extension 26 provided with a nozzle 27 to which aflexible gas tube is attached.

Various changes may be made in detail. form and arrangement of partswithout deviating from my invention.

Having thus described my invention, I claim 1. A sad iron having ahollow body, the bottom walllof said body having thickened portionsadjacent the side walls, longitudinal heat conducting ribs extendingabm'e said thickened portions, lateral air inlet passages in saidportions. arches extending inwardly from said thickened portions andforming continuations of said air passages, the inner ends of said airpassages being upwardly inclined. a burner, having lateral out-lets,longitudinally and centrally disposed in said body, means for securingsaid burner and means for supplying gas to said burner.

2. A sad iron having a hollow body, the bottom wall of said body havingthickened portions adjacent to the side walls and a centrally disposedthinner portion between the same, longitudinal heat conducting ribsextending above the thickened port-ions, arches extending inwardly fromsaid thickened portions, lateral air inlet passages passing through saidthickened portions and through the arches, grooves in said thinnerportion forming extensions of said air pasburner.
